“…It will be shown that when the electrical charges come from the process of radioactive decay, i.e. alpha or beta decay, it is possible to extend the Rayleigh limit of charge density, and an expression is derived for the critical size of the bubbles, which can be used to predict the maximum size of tritium bubbles from the coalescence and growth process in liquid Pb-16Li blankets for its extraction in fusion reactor technologies [2,3].…”

The Rayleigh density limit and its significance with regard to coalescence and growth of radiative bubbles is discussed. It is shown that taking into account the kind of radioactive decay, i.e. alpha or beta decay, the Rayleigh density limit results in a critical radius limit for the coalescence and growth of radiative bubbles. Because the size of bubbles is one of the most important parameters to be considered in transport and extraction technologies, the present study has important application for the computational modelling of tritium extraction from liquid Pb-16Li blankets for fusion reactor technologies.
